The above numbers were obtained using a debug build made with dmd.
The following numbers are from a optimized build with ldmd2

First Execution (cold cache) :

Initializing Heap:     17.4 ms
Generating Bytecode:    0.7 ms
Executing Bytecode:     5.3 ms
Converting to CTFE-EXp: 5.1 ms

Second run (warmer cache) :

Initializing Heap:     16.9 ms
Generating Bytecode:    0.3 ms
Executing Bytecode:     5.3 ms
Converting to CTFE-EXp: 4.9 ms
